(Nasdaq: ENZN) announced today that it has revised its revenue guidance for the fiscal year (FY) ending June 30, 2005 based on reduced expectations for North American sales of ABELCET(R) (amphotericin B lipid complex injection), the Company's antifungal product. The revised expectations reflect weaker-than-anticipated demand for ABELCET and increasingly competitive market conditions. Enzon currently expects North American sales of ABELCET of $55 million to $60 million for the FY ending June 30, 2005, as compared to the Company's prior guidance of $69 million to $73 million. As a result of the revised ABELCET guidance, the Company now expects combined product sales for its four internally marketed products of $100 million to $115 million for the FY ending June 30, 2005, as compared to Enzon's prior guidance of $110 to $125 million.

Such factors include Enzon's ability to compete effectively in an increasingly competitive market, the existence of continued demand for Enzon's products, as well those factors described in Enzon's Form 10-K/A and Forms 10-Q on file with the SEC. These factors should be considered carefully and readers are cautioned not to place undue reliance on such forward-looking statements.
